The Legend of Zelda: Oracle of Ages

Transcend the very fabric of time with the Harp of Ages. Rescue Nayru,
the Oracle of Ages, to save the Land of Labrynna from Veran, Sorceress
of Shadows, who will pitch the world into an endless night.

Travelling through time presents Link with unique challenges. If a river
blocks Link's path in the present, he can travel to the past and move a
stone, redirecting the flow of water. If he plants seeds in the past,
he'll find full-grown trees and vines when he returns to the present.
